Programmable DC Power Supply 62000L Series User’s Manual

 

1-2 

 

 

 

Easy-To-Use Control Knob 
The knob on the 62000L series utilizes photo-interrupted technology. It’s durable and 
reliable. The enhanced sensitivity completely replaces the need for numerical input keys. 

 

 

 

 

Highly Readable Display 

 

High Accuracy and Resolution 

 

Fast Response Time   
The oscilloscope test below measures the time for the output voltage to recover to within 
15 mV of nominal output voltage. The overshoot change is a result of a 7 A to 3.5 A load 
step, with the recovery taking only 13.6 us.
